C60 molecules on a gold substrate appear more complex than their graphene counterparts, but have much more ordinary electronic properties. This is now shown by measurements with ARPES at BESSY II and ...
The nano-IR imaging set-up for studying the moiré graphene lattice. (Courtesy: G Ni) Researchers at the University of California at San Diego (UCSD) are the first to have used infrared nano-imaging to ...
The phenomenon in physics known as “Floquet states”, which have now been observed in graphene for the first time, as envisaged by artist Lina Segerer. This image “Dirac Cones I” explores the concept ...
The number of graphene layers determines specific properties. Both single-layer and bi-layer graphenes are zero band gap semiconductors because of the association between conduction and the valance ...
For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the ...
With a flash of light, scientists have been able to control graphene's electrons, confirming a long-suspected effect in quantum materials. A new study, headed by the in collaboration with colleagues ...
Scientists have observed a quantum fluid of electrons in graphene for the first time, showing near-perfect fluid behaviour and shedding light on a quantum physics puzzle. In a collaborative effort, ...
Graphene consists of carbon atoms that crosslink in a plane to form a flat honeycomb structure. In addition to surprisingly high mechanical stability, the material has exciting electronic properties: ...
